The Jacksonville Sheriff's Office, along with state and federal officials, announced they've arrested 10 individuals (9 men and 1 woman) who were part of a violent street gang.

Two of the men, Henry Hayes, 18, and Kquame Richardson, 18, were both arrested and charged with the murder of 22-month-old Aiden McClendon. On Thursday, police announced RICO charges will be added to their rap sheet.

"I wouldn't say that this particular incident, the Aiden McClendon case, actually started it, but it was a big step forward in that case where we really started to take a hard look and see a lot of the same players and begin to make the connection of them being involved in the same type of organization," said Sheriff Mike Williams with the Jacksonville Sheriff's Office.

The two involved in McClendon's murder, plus eight other individuals, were all part of a violent street gang which called itself Problem Child Entertainment (PCE). It masqueraded as an entertainment company, but its members committed violent crimes including murder, attempted murder, aggravated battery, armed robbery, theft, and drug sales.

Police worked with the Florida Department of Law Enforcement, the Federal Bureau of Investigation and the State Attorney's Office for over a year to bring this violent gang's "reign of terror" to an end.

Williams said that though there are always additional players that affiliate themselves with gangs, the investigation efforts were focused on those who were most dangerous and those were committing the dangerous crimes within the gang.

The Aiden case is just one murder confirmed to be affiliated with the PCE gang. NIBIN was used on shell casings found at the murder scene to help connect the men arrested to the murder.

"We've disabled an organization that as the Sheriff has told you has committed crimes throughout the community," State Attorney Melissa Nelson said.
